SPECIFICATION forming part of Letters Patent No. 483,010, dated September 20, 1892 Application filed July 5, 1888. Serial No. 279,049. (No model.)

To all whom it may concern.-

Be it known that we, EDWARD B. PARK- HURST and Fos'rEE HAM, both of Woburn, county of Middlesex, State of Massachusetts, have made certain new and useful Improve ments in Cash Indicators and Registers, of which the following is a specification, refer ence being had to the drawings accompanying and forming a part hereof, in which Figure 1 is a plan view. Fig. 2 is a front elevation, the outer case being shown in section and a portion of the front of the drawer being broken away for greater clearness. Fig. 3 is an end view, the drawer being shown in section to expose the drawer-locking mechanism. Fig. 3 is a detail of the end of the lever for locking the registering-wheel and its connection with the parts which actuate it. Fig. 4 is an end elevation designed to show the key mechanism and with the other parts removed. Fig. 5 is a section on line y y, Fig. 3. Fig.6 is a detail, partly in section, of the device for locking the machine. Fig. 7 is a section on line 0200, Fig. 6. Figs. 8 and 9 are respectively a plan and side view of the bar which operates to lock the remaining keys while one key is being used.

The object of our invention is the construction of an accurate and efficient machine which cannot be tampered with for indicating the amount of cash deposited in the money-drawer each time it is opened and for registering the total amount deposited in a given time; and it consists of a series of keys provided with numbers corresponding with the amounts of cash to be deposited and arranged to actuate tablets correspondingly numbered which are thrown up into sight as the keys are depressed, each of said keys being also in connection with the registering apparatus, which will show the total amount indicated by the depression of the keys; and it consists, further, in numerous details of construction and arrangement by which the accurate and certain working of the device is insured, all of which will be hereinafter more particularly set forth.

IVe will describe our invention as it is embodied in the machine shown in the accompanying drawings, using like letters of reference to indicate like parts throughout the same.

A represents the base, which may be of wood, on which the machine rests.

B represents the outer case, in which the machine is placed, and the lower part of the case B is provided with a cash-drawer C. A strip of glass D is inserted in front and rear of the case near the top, (see Fig. 2,) so that as the tablets are thrown up they will be exposed to view.

On the base A are secured the upright frame portions, which support the keys and other mechanism. The uprights a support the pivots or shafts Z), on which the key levers cl are mounted. These key-levers are bent at their forward ends, which support the keys so that the keys may be arranged in a bank and yet each be separate from the others and be in a position where it may be readily touched with a finger, as shown, Figs. 1 and 8. The inner ends of the key-levers projectinwardly and have a downwardly-projecting rack 0, against which a pawl c, Fig. at, acts. The pawl e is pivoted near the base of the upright E, and has a rearward projection to which a spiral springf is attached, said spring acting to press the engaging end of the pawl e into the teeth of the rack o. By this arrangement the key cannot be partially depressed and then raised, but must be fully depressed, so as to bring the projection g at the lower end of the rack c in contact with the pawl c. This projection g is sufficient to throw the pawl 6 back until it is caught by the hook of the latch it, which is pivoted about midway of its length to the upright E. (See Fig. 4:.) The latch 7L now holds the pawl 6 clear of the rack c and the inner end of the key-lever is free to drop, raising the key to its normal position. A portion of the key-lever 61 extends rear wardly of the rack c and as the key is depressed comes in contact with a tablet-rod j, forcing up the tablet-rod and exposing the tablet on the upper end of the rod to view. The tablet-rods are arranged to slide in apertures in the cross-pieces F of the uprights E. The tablet-rods are placed rearwardly of the stop-bar H, which is set across the top of the machine, as shown, Fig. 5, and has a slight lateral movement in the upright supports E. A spiral spring 70, Fig. 1, which is secured at one end to a stationary part of the machine and at the other to a projection on the stopbar, tends to pull the stop-bar toward the right, Figs. 1 and 5. At the rear of the stopbar and projecting therefrom are a series of arms Z, Fig. 1, of varying lengths, each projecting to the tablet-rod with which it is designed to co-operate. The ends of these proj ections Z are beveled in cross-section, as shown by the dotted lines, Fig. 5, and each tabletrod is provided with a correspondingly-beveled stop m, which as the tablet-rod is raised comes in contact with the beveled end of the projection of the stop-bar and forces the stopbar toward the left against the tension of spring 7c. above the projection Zthe spring 75 forces the stop-bar H toward the right and the projection Z is carried under the stop m and the tabletrod isheld in its raised position. hen a key is depressed the next time the machine is used, the tablet which is up must drop back as another tablet is raised. The tablet-rodis free to drop provided the projection Z is shifted to the left a sufficient distance to clear the stop in on the tablet-rod, but the upward movement of the succeeding tablet-rod will not move the stop-bar H and its projections sufficiently to insure the dropping of the preceding tablet-rod. To have, therefore, devised the following mechanism for giving the stop-bar H an additional movement toward the left, which is as follows: On the red I), which supports the key-levers, a table a is pivoted, said table being provided at either end with downward projections I), through which the rod 1) passes, (see Fig. 2,) forming bearings for the table. From one of these bearings b an arm 0 projects upwardly, and to the upper end of this arm a horizontal rod d is pivoted at 6. (See Figs. 1, 2, and 3.) The rear end of the rod (1' slides in an aperture cut in a projectionf on one of the up rights E. (See Fig. 5.) The rear end of the bar d is enlarged and is beveled at g, as shown, Fig. 1. The end of the stop-bar H passes through the upright E above the projection f andis turned downwardly, as shown at h, Fig. 5, the downwardly-projecting end being beveled, as shown at t, Fig. 1, to correspond with the bevel g on the rod (1'. The bevel z" is in such a position that when the bar d is drawn forward its bevel will come in contact with the bevel 2'', thus forcing the projection h and the bar H outwardly, or toward the left, a distance sufficient to carry any of the projections Z of the bar H out of the path of the stops at on the tablet-rods, thus allowing a tablet-rod, which may be up, to drop freely. The bar d is drawn forward each time a key is depressed, since the depression of the key raises the table a, which rests on the key-levers cl, (see Fig. 3,) and throws the upright lever c, which is integral with or fast to the table-bearings forward,

As soon as the stop m has passed thus drawing forward the bar cl, as will be clear. The bar d is actuated in the opposite direction, when the key rises, by means of a spring 25, Fig. 1, which is fast at one end to a projection on the bar and at the other to a cross piece of the frame. As there are two banks of keys in the machine shown, the one having a unit of 5 and the other a unit of 50, which are substantially separate and are duplicates of each other, the same mechanism for shifting the stop-bar H is provided for each bank of keys, as will be clear from Fig. 2, and a similar downward projection h from the bar H is provided to co-operate with a horizontal bar 61, operated by the bank of keys having 5- for a unit, shown at the right. lVe mention this for the sake of greater clearness, since the description above given had reference more particularly to the mechanism of the bank of keys shown at the left.

For the purpose of registering the total amount of cash deposited a registering apparatus is provided for each bank of keys, the two sets of registering apparatus being substantially the same and being constructed as follows: An nprightj', Figs. 1 and 2, is secured to the base A. To the top of this upright a bent lever is pivoted at Z and projects over the key-levers, the free end of the bent lever being received in a slot m, Fig.1, out vertically in a bent upright n, which serves as a guide to the bent lever 7a. A pawl 19 is pivoted toa projection on the upper edge of the bent lever 70 and is pressed against the ratchet-teeth of the registering-wheel r by means of a leaf-spring s, which is set behind the pawl on the bent lever 7c. (See Fig. 2.) It will be clear that as the lever 70 is raised the registering-wheel will be turned, and the shape of the lever is such that the pawl is raised by the depression of each key a distance sufficient to cause the registering-wheel to register the amounton the key depressedthat is, the key-lever of the key marked 50 will not come in contact with the register-lever 70 as soon as will the key marked 300, and will not consequently raise the lever as high, and so will not cause the wheel to register as much, while the key marked 500, being nearer the fulcrum of the registering-lever, will raise it higher than will any of the other keys, and consequently will register a greater amount. The register-wheel r is connected with the companion register-wheel u by means of a gear and pawl-and-ratchet mechanism of well-known construction, so that each complete revolution of the wheel 0" causes the companion wheel a to register one. As the key-levers cannot be pumped that is, thrown up and down-without operating the machine because of the ratchet c and pawl e at the rear end of each lever, already described, the key must be fully depressed each time it is used, and consequently the register-lever 70' will register only the amount indicated on the key which is used. When, however, the key has been fully depressed, throwing up the rear end of the keylever and forcing back the pawl 6 into the hook of the latch h, the key-lever is then free to drop, and in that condition that key might be pumped, thus moving the registering ap paratus and causing it to register wrongly. To obviate this difficulty, we have provided the followingmechanis1n,bywhich,afterakeyhas been fully depressed and the pawl e forced back into the hook of the latch h, the registering apparatus will belocked and held stationary until the rear end of the key-lever has again fully descended. This mechanism consists of an upright lever to, Fig. 3, of the shape shown, pivoted at its lower end on the rod 1), (see Fig. 2, and provided at its upper end with two camslots 19 The slot a receives a pin 0 set on the arm or lever c. The cam-slot 5 receives a pin d set on the end of the horizontal lever 6 which is pivoted to the top of the upright f. The lever e projects at its inner or rear end over the register-wheel r, and when said inner end is depressed it comes in contact with the teeth of the register-wheel and prevents that wheel from being moved forward. The lever e is depressed at the end of the full movement of a key-lever when a key is de pressed and is held in this position while the key is rising again toward its normal position, and until the key has nearly reached its normal position, at which time the pawl c is freed and comes in contact with the ratchetc-that is, the register-wheel is locked by the lever e at all times when the pawl c is out of contact with the ratchet c,thus rendering it impossible for the machine to be so manipulated as to register inaccurately. The rear end of the lever c is thrown down when a key is fully depressed by reason of the movement of the lever 0, already described, which when its pin 0 has moved through the slot a moves the lever to, causing the pin d to rise in the cam-slot b thus raising the forward end of the lever a and forcing the rear end against the ratchet on the register-Wheel T. It will be clear that as the key rises again the register-wheel will remain locked until the key has nearly reached its highest position, the pin 0 as the the key rises, traveling back through the slot a without moving the lever to, thus allowing the lever e to remain in contact with the register-wheel, locking the same. As it is important that a second key should not be operated until the previously-operated one has been reset to its normal position, we haveprovidedalocking-barJ, (shownin detail, Figs. 8 and 9,) which is provided with a series of teeth 9 for each bankof keys, said teethhaving spaces between them sufficient in size to allow the rear ends of the key-levers to pass up and down between the teeth. Before a key has been used the rear end of its lever lies below one of the spaces between the teeth 9 but after the key has been used and while the tablet which corresponds to it is up the rear end of its lever rests on the top of one of the teeth or projections 9 while each of the other key-levers lies directly belowa tooth g This arises from the lateral movement of the locking-bar J, which slides in apertures in the uprightsEateitherendofthemachine. Alever 7L2, Fig. 5, is pivoted to aprojection onthe frame and at its lower end bears in a notch 2' cut in the locking-bar J, while its upper end is provided with a springj secured at one end to the lever and at the other to the frame of the machine. The lever 7L2 tends to move the bar J toward the left. On the underside of the bar J another notch k is out, which receives the end of the bell-crank lever P, which is pivoted at m to a projection on the base of the frame. The other end of the bell-crank lever Z rests on a vertical bolt n which is free to move vertically in an aperture in the base A, and which extends through the top of the drawer-case, as shown, Figs. 3 and 5. The lower end of the bolt n rests on the rear end of an arm 19 which is fast to the rear of the drawer 0. That portion of the arm 13 with which the bolt n comes in contact is beveled at the rear end, as shown by the dotted line at T Fig. 3, so that as the drawer is moved forward or out the bevel 0' passes under the bolt of, allowing the bolt to drop, freeing the bell-crank lever Z and allowing the lever 7t and its spring to move the locking-bar J toward the left, thus carrying the projections or teeth g over the rear ends of the key-levers which are not in use, and thus preventing these levers from being used or their keys depressed. When the drawer is closed, the bevel r is forced under the bolt 91 thus raising the bolt and forcing the locking-bar J back toward the right, thus freeing the key-levers which were locked down and allowing the lever of the key which was used to drop through a space between the teeth g into its normal position. The lever 71 carries the bell-hammer s and when the bar J is released, as described, the movement of the lever 7L causes the hammer to strike the bell 73 thus causing the bell to ring each time the I drawer is opened.

A pawl 10 which is pivoted to a lug on an upright K of the frame (see Fig. 5)just above and at one side of the locking-bar J, is received in a notch w in the said bar J. The pawl 10 is offset at its free end, (see Fig. 1,) so as to rest in said notch 10 and has a downwardly-projecting arm a which rests on the head of the vertical bolt Z2 said bolt being free to move in an aperture through the base A and the drawer-case in the same manner as is the bolt n The lower end of the bolt 19 also rests on a portion of the arm p said portion of the arm 13 being enlarged and beveled, as shown by the full lines, Fig. 3. As the drawer moves out the bolt 11 is forced upward, thus freeing the pawl a from the notch 10 and allowing the lockingbar J to move toward the left. The object of the pawl to is to insure the ringing of the bell each time the drawer is opened. The bell will ring whenever the locking-bar J is suddenly freed, al-

lowing the spring-lever 7L2, which carries the bell-hammer, to move quickly. This will occur whenever the pawl 10 is raised from the notch 10 the pin a being already down and the bell-crank lever Z being free, and it is impossible by any manipulation of the drawer to open it without first dropping the pin 91. and then raising the pin 6 and the pawl a and freeing the bar J. The forward end of the arm p is in contact with the lower end of the vertical bolt 0 which moves vertically in a hollow standard 01 resting on the base A between the banks of keys, as shown, Fig. 2. The lower end of the bolt 0 also passes through an aperture in the base A and in the top of the drawer-case, as shown, Figs. 2 and 3. The top of the bolt 0 is provided with a cross piece or head e with the under side of which a projection f from each of the tables a is in contact. (See Figs. 1 and 2.) As the key is depressed and either of the tables a raised the bolt 0 is also raised, freeing its lower end from the arm 19 and allowing the drawer to be opened. A leaf-spring 9 Fig. 3, is screwed to the inside of the rear end of the drawer-case and bears against the rear end of the drawer C. The drawer is closed against the pressure of this spring, and as soon, therefore, as the bolt 0 is raised the drawer is forced out part way by the pressure of the spring g It will be clear that if the bolt 0 be locked down so that it cannot be raised the drawer cannot be opened, the tables a cannot be raised, and the keys cannot be worked, so that by locking the bolt 0 the entire machine is locked. To look the bolt 0 we have provided a spring-impelled bolt 713, Fig. 6, which is received;in a hollow projection 11 on the standard (1 The bolt h is provided with a screwthreaded shank which extends through an aperture in the front of the projection i and inside the projection i a spiral spring encircles the bolt 71 and acts to impel the bolt 77. against the vertical bolt 0 The inner end of the bolt ha is beveled and is received in a corresponding notch in the vertical bolt 0 so that when the bolt it is in the notch in the vertical bolt the vertical bolt cannot be raised and the machine is locked. By applying the key 7' which has a threaded aperture to receive the projecting end of the bolt it to said bolt 71/ and turning the key until the bolt h is withdrawn from the vertical bolt 0 the machine is unlocked and ready for use, as shown, Fig. 3.

The locking-bar J is notched underneath, as shown at W, Fig. 9, and the rear end of the latch it rests in one of the notches. lVhen the drawer C is open after a key has been depressed the latch rests in the notch toward the right, and when the drawer is closed the bar J moves toward the right until the latch rests in the other notch, this movement acting to depress the rear end of the latch and raising its front end, freeing the pawl e from the latchhook and allowing the pawl to come in contact with the teeth of the ratchet 0.

As a means of preventing more than one key from being used at a time the pendantpieces Z Fig. 5, may be used. These pieces are pivoted to across portion of the frame and project downwardly nearly to the key-levers. As a key-lever rises between them they have play enough to separate sufficiently to allow it to pass up, but cannot separate sufficiently to allow more than one key-lever to pass up at a time. As this arrangement of pendants forms no part of our invention and is not necessary to the operation of our machine, we do not deem it essential to describe it with greater detail.

The key marked 0, Fig. 1, isa blank whose lever does not operate the register-lever 7a or a tablet-rod and is for convenience in opening the drawer without registering or indicating.

The pawl 6 consists of astrip of metal which serves as a pawl for all the key-levers in each bank, as will be clear from Fig. 2.

As will be obvious, more than two banks of keys may be employed, if desired, and a bank having a unit of one will often be found necessary or desirable.
